Got to the point of building LLVM 15.0.6 on the VisionFive 2 - it's going like a rocket compared to doing the same in QEMU (even though I emulated many more cores with QEMU!)
CPU Temperature seems to be sat at about 65 deg C, 8GB seems to be plenty of RAM for building with 4 processes. Seems to have got 25% of the way through the build in 30 minutes. Note sure how to check what speed the cores are running at / if they're throttled.
Better than I'd expected, will probably redo this build once I have a heatsink / fan and NVMe to see how much faster it could be.
@conor Yeah, I just want to work on JIT so I don't need anything else.
I put together a proof of concept that Numba could JIT Python on RISC-V with Qemu a couple of weeks ago: https://github.com/gmarkall/numba/commit/7c8c5e7201d9679eb9a765f35117a9f669798322
Since I got that far, I felt it was justified to invest in some real hardware to make a serious attempt at RISC-V support in Numba / llvmlite in early 2023, hence getting the VF2.
